Syntax

public struct ARCollaborationDataBuilder : IDisposable, IEquatable<ARCollaborationDataBuilder>

Remarks

This struct can be useful if you receive data through a stream. If you already have all the bytes, use a ARCollaborationData constructor instead. This struct represents a native resource and must be explicitly disposed when no longer needed. While this struct is not thread safe, you can construct, Dispose, and Append from any thread.

Properties

hasData

Whether the ARCollaborationDataBuilder has allocated any data. If true, this struct must be disposed to avoid leaking native resources. If false, this struct either never allocated memory (with Append(byte[], int, int) or Append(NativeSlice<byte>)) or it has already been Dispose()d.

Declaration

public bool hasData { get; }

Property Value

Type	Description
bool

length

The number of bytes owned by this struct.

Declaration

public int length { get; }

Property Value

Type	Description
int

Methods

Append(byte[])

Appends all bytes of the array buffer to an existing array of bytes.

Declaration

public void Append(byte[] buffer)

Parameters

Type	Name	Description
byte[]	buffer	A buffer containing bytes to append.

Exceptions

Type	Condition
ArgumentNullException	Thrown if buffer is null.

Append(byte[], int, int)

Appends size bytes of the array buffer to an existing array of bytes.

Declaration

public void Append(byte[] buffer, int offset, int size)

Parameters

Type	Name	Description
byte[]	buffer	A buffer containing bytes to append.
int	offset	The offset within buffer to start appending bytes to the internal array.
int	size	The number of bytes from buffer to append. Must be less than buffer.Length + offset.

Exceptions

Type	Condition
ArgumentNullException	Thrown if buffer is null.
ArgumentOutOfRangeException	Thrown if size is less than zero.
ArgumentOutOfRangeException	Thrown if offset is less than zero.
InvalidOperationException	Thrown if size is less than zero or greater than the length of buffer.

Append(NativeSlice<byte>)

Appends bytes to an existing array of bytes.

Declaration

public void Append(NativeSlice<byte> bytes)

Parameters

Type	Name	Description
NativeSlice<byte>	bytes	An array of bytes to append to the existing data.

Exceptions

Type	Condition
ArgumentException	Thrown if bytes does not reference valid data.

Dispose()

Releases the native resource.

Declaration

public void Dispose()

Equals(object)

Compares for equality.

Declaration

public override bool Equals(object obj)

Parameters

Type	Name	Description
object	obj	The object to compare for equality.

Returns

Type	Description
bool	true if obj is of type ARCollaborationDataBuilder and compares equal to this instance with Equals(ARCollaborationDataBuilder). Otherwise, returns false.

Overrides

ValueType.Equals(object)

Equals(ARCollaborationDataBuilder)

Compares for equality.

Declaration

public bool Equals(ARCollaborationDataBuilder other)

Parameters

Type	Name	Description
ARCollaborationDataBuilder	other	The ARCollaborationDataBuilder to compare against.

Returns

Type	Description
bool	true if all fields of this instance compare equal to other. Otherwise, returns false.

GetHashCode()

Computes a hash code suitable for use in a Dictionary or HashSet.

Declaration

public override int GetHashCode()

Returns

Type	Description
int	The hash code for this instance.

Overrides

ValueType.GetHashCode()

ToCollaborationData()

Converts the bytes accumulated through calls to Append(byte[], int, int) to an ARCollaborationData. The caller is responsible for disposing the returned ARCollaborationData.

Declaration

public ARCollaborationData ToCollaborationData()

Returns

Type	Description
ARCollaborationData	A new ARCollaborationData constructed from the bytes added to this ARCollaborationDataBuilder.

Exceptions

Type	Condition
NotSupportedException	Thrown if ARCollaborationData is not supported. Check for support with supportsCollaboration.
InvalidOperationException	Thrown if hasData is false.

Operators

operator ==(ARCollaborationDataBuilder, ARCollaborationDataBuilder)

Compares for equality. Equivalent to Equals(ARCollaborationDataBuilder).

Declaration

public static bool operator ==(ARCollaborationDataBuilder lhs, ARCollaborationDataBuilder rhs)

Parameters

Type	Name	Description
ARCollaborationDataBuilder	lhs	The left-hand side of the comparison.
ARCollaborationDataBuilder	rhs	The right-hand side of the comparison.

Returns

Type	Description
bool	true if all fields of the instances are equal. Otherwise, returns false.

operator !=(ARCollaborationDataBuilder, ARCollaborationDataBuilder)

Compares for inequality. Equivalent to !Equals(ARCollaborationDataBuilder).

Declaration

public static bool operator !=(ARCollaborationDataBuilder lhs, ARCollaborationDataBuilder rhs)

Parameters

Type	Name	Description
ARCollaborationDataBuilder	lhs	The left-hand side of the comparison.
ARCollaborationDataBuilder	rhs	The right-hand side of the comparison.

Returns

Type	Description
bool	true if any of the fields of the instances are not equal. Otherwise, returns false.
